Specification of Letters Patent.

Patented Nov. 6, 1906.

` To all whom t may concern.-

Be it known that I, WALTER IRvING BROCK, a citizenl of the United States, and a resident of Erie, in the county of Erie and State of Pennsylvania, have invented a new and Improved Freight-Car, of which the following is a full, clear, and exact description.

My invention relates to freight-cars; and my object is'to provide a car capable of transporting liquid or solid material and which .shall be strong in construction, durable in use, and adapted to be freely and quickly loaded and unloaded.

Other objects accomplished by my invention are hereinafter more particularly set forth'. Y Such objects l accomplish by the means illustrated in the accompanying drawings, in Which drawings like characters of reference indicate likeparts throughout the views, and in which- Figure 1 is a side elevation, partly broken away, of a car embodying my invention.

Fig. 2 is an end view of the car shown in Fig...

1. F1g. 3 is a vertical transverse section taken on the line3 3'of Fig. 1. A Fig.4is a sectional side elevation of the end of a car embodying myinvention. Eig. 5 is a transverse Section taken on the line 5 5 of Fig. 4. Fig. 6 is a side elevation of a locking-lever adapted to support the trap-doors of a hopper, and Fig. 7 is a' perspectiveview of a trapdoor detached from the bottom of the hopp As illustrated in the drawings, 1 represents .the main frame of a car,mounted upontrucks 2 ofvordinary construction.

The body of the car consists of a cylindrical shell 3, having a central bearing-ring 4, Which is supported upon rollers 5,journaled upon a frame 5, extending transversely of the main frame of the car. The body of the car is provided withconical ends 6, having heads 7 secured thereto, as shown in Fig. 4..

'ons 8 are provided on their inner ends With flan es 8, which are secured toheads 7 of the bo y of the car by means of rivets 7a.

Thetrunnions 8 are supported upon rollersV 9, having pivot-pins 9a, which engage corresponding apertures formed in spacing-rings 9b and adapted thereby to hold the rollers 9 at the desired distance from each other. The rollers 9 are arranged within bearing-boxes 10, which are mounted upon standards '12, Secured to each end of the main frame of the iianges 24 of the hatches.

drawn over the hatches 23 or removed j car. Caps 11 are secured to the bearingboxes by means of stud-bolts 11a. The standards 12 may` be of vany suitable construction, but consist, preferably, of a vertical .outer transverse wall having an inclined drical body 3 on its trunnions 8. The body of* the car, however, is held in its normal posi tion by means of locking-bolts 21, which en gage corresponding apertures formed in blocks or heads 22, secured to the conical ends 6 of the body of the car. Connecting-rods 2O are secured at their inner ends to the lockingbolts 21 and atv their outer ends to crankf arms 18, formed on the crank-shafts 18, which shafts are journaled in bearing-boxes 19, secured to the ends of the standards 12. The locking-bolts 21 are brought into engagement with the blocks 22l or released therefrom by rotating lthe crank-shafts 18 by means of handles 18b formed' thereon.

Hatches 23 are formed in the cylindrical body of the car, as shown in Fi 3. These hatches are provided with en anges orA combings 25 and side flanges 24, having their upper ends 24a lying in a horizontal plane and offset from the body of the flanges. Hatch-covers 26 are arranged over the hatches 23 and have attached to their outer edges racks 27, which mesh with the teeth vof pinions 28, mounted upon transverse shafts 29, having hand-wheels 30, secured to the ends of said. shafts. The transverse shafts 29 are journaled in suitable bearings secured to standards 32, which are attached at their lower ends to the'main frame of the car and connected at their upper ends by means of transverse bars 33. Longitudinal recesses 27 a are formed on the racks 27 and are adapted to engage the offset edges 24a of the side Thehatch-covers 26 are thereform by rotating the shafts 29 so that the pinions 28, mounted on said shafts, will IOO IIO

move the racks 27 and the hatch-covers 26,.

secured thereto, in the direction desired and in accordance with the direction in which the hand-wheels 30, mounted upon said transverse shafts 29, are turned. The shafts 29 are arranged in advance of the ends of the cylindrical portion 3 of the car-body, and the ends of the racks 27, secured to the hatchcovers 26, are extended beyond the ends of the hatch-covers, so'as to be in constant engagement with the pinions 28, mounted upon the transverse shafts 29. When the hatchcovers 26 are drawn outward, so as to uncover the hatches23, the racks 27 move along the flanges 31a, formed on the lon itudinal beams 31,4 which are connected to t e upper ends of the standards32, and thereby support the hatch-coversv 26 when they are removed from the cylindrical portion of the body of the car. I prefer to make the edges 241`or`v the hatch-flanges 24, and also the portion of the racks 27 in contact therewith, slightly ta ering, so that the hatch-covers 26 may there ybe drawn suiiiciently tight onto the edges of the flanges of the hatch, and in most instances I preferv to lace a stop of any suitable construction on t e beams 31 to prevent the hatch-covers from moving too far outwardly from the body of the car. Ladders 44 extend' from the main frame of the car to the outer ends 'of the standards 32, so as to enable the hand-wheels 30 to be readily operated. A foot-plate 33L is secured to the transverse'bars 33 and is made, preferably, of the same width as the hatch-covers 26 and of the same length as the side beams 31, which are secured to the upper ends of the standards 32. When the hatch-covers are removed in the manner described and the locking-bolts 21 are released from the blocks 22,'the body of the car may be rotated on its trunnionsby means of the wheels 16, so as to uickly unload the contents of the cylindrica body kof the car into a hopper 34, which is secured to the main frame of the car. The ends 34a of the hopper are inclined, so as to correspond to the conical ends tlius formed on the cylindrical body 3 of the car, and' the side walls of the hopper 34' extend in4 circular lines concentric to the cylin` drical body of the car. The lower portionsl 34'b of the sidewalls of the hopper 34 extend vertically andsupport longitudinally-movable bars .39, having bearingsin yokes 41, se

cured to tli'e vertical walls 34b of the hopper.

A central longitudinal beam extends length-y wise of the main frame of the car andconsists, preferably, of side beams 37, provided with upper and lower flanges 37 a, to which are secured'to and bottom plates 38. Trapdoors 35 are 'nged at their inner edges to said central longitudinal beam by means of hinge-pins 36, and the outer edges of saidA doors are providedl with latches 35a, rigidly secured thereto 'andl adapted 'to engage offset lugs 40, formed on the locking-bars 39.

Links 42 are pivoted at one end to the bars 39 and at their opposite ends to cranks 43, Jformed on rock-shafts 43, which are mounted in suitable bearings on the main frame 1 of the car and provided with handles 43h. By rotating said handles the locking-bars 39 move longitudinally to a limited extent in their bearings'41, and the lugs 40 of said bars are released from engagement with the latches 35a of the trap-doors 35 of the hopper and permit said doors to drop downward into a vertical position, as'indieated by d'otted lines in Fig. 3. A bulkhead 3a may be extended across the central portion of the body 3 of the car, so\ as to form two separate and' independent compartments Aadapted to hold cargoes of different kinds* at the same time. When this device is@ in use, the enlarged hatches, extending nearly the entire length of the cylindricalv body of the c'ar, en* able the body to be uickly loaded and unloaded. If desired, t e cylindrical body of the car and the hopper may be load'ed with cargoes of diiiierent" kinds. I'n such cases the cargo of the hopper is iirst unloaded, andthe contents of the cylindrical bodyof the car may then be unloaded into the hopper andE from thence into receptacles of any suit-able character placed beneathl the bottom of the hopper connected therewith.

Having thus described my invention, what I claim as new, and? desire to secureby Letters Patent, is
